Face it, when something you depend on fails you it can be extremely frustrating. Have you had the experience of putting your key into your car only to find yourself unable to get it started? Have you ever tried to surf the web only to find you have no working internet connection? Have you ever wanted to mow your lawn and discovered that no matter how many times you pulled the cord, you could not start your mower? It is amazing how dependent most people are on the conveniences of modern day electronics. When one or more of them is unavailable it can be a significant interruption. Sometimes the solution is fast and simple. A reconnection to the web may be as simple as plugging in an unplugged router. Getting iPod repair or iPhone repair is usually a cost effective and fast service. Tending to a broken washer,dryer, or refrigerator is often a bit more involved. A faulty transmission is not only a pain, but a financial burden as well. As much as people depend on modern technology there can be serious consequences if it fails. Chances are everyone has experienced a technology or equipment failure at one point or another but predicting which mechanism or when is not very likely. One way to head off a potentially costly fix is to invest in a maintenance warranty or service agreement, but is this always a good idea?
